Question: I have a VMAR ARF model with an Engine Mount with no clamps. I bought my model in the summer or fall of 2004. Why does my engine mount not have clamps and how do I use it with my engine?

Answer: In response to some feedback from modellers we produced a limited number of models in the summer and fall of 2004 with no clamps to gauge public acceptance in advance of our 2005 production schedule. A set of four motor mount bolts, nuts and washers or 4 self tapping screws were included with each such ARF in lieu of the clamps. Position your engine so that the engine lug forward edge is about 15/16" back from the forward end of the engine mount.

If your model came with bolts, mark and then drill the mount with a 5/32" bit and bolt the engine directly to the engine mounts using the 4 bolts, nuts and washers provided.

• We have produced an illustrated Important Information sheet of supplementary instructions for the Stinger and loaded this information on the Stinger portion of our web site.

• Although this document relates directly to the Stinger, it is applicable to other VMAR models using bolts and nuts with the composite engine mount without clamps.

If your model came with self tapping screws, drill the mount with a 1/16" drill bit to make pilot holes and then expand the holes to about 2/3 of the diameter of the screws provided. Do not over-enlarge the holes.
